This paper presents an architecture for the computation of the atan(Y/X) operation suitable for broadband communication applications where a throughput of 20 MHz is required. The architecture is based on LUT methods and achieves lower power consumption with respect to an atan(Y/X) operator based on CORDIC algorithm with a lower latency. The proposed architecture can compute the atan(Y/X) with a latency of two clock cycles and its power consumption is 49% lower than a CORDIC with the same latency.
